+    (description "The Link Grammar Parser is a syntactic parser of English,
+Russian, Arabic and Persian (and other languages as well), based on Link
+Grammar, an original theory of syntax and morphology.  Given a sentence, the
+system assigns to it a syntactic structure, which consists of a set of
+labelled links connecting pairs of words.  The parser also produces a
+\"constituent\" (HPSG style phrase tree) representation of a sentence (showing
+noun phrases, verb phrases, etc.).")
